HENRY BRANCHLER, OF GREENSBURG, PENNSYLVANIA, ASSIGNOR OF ONE- HALF TOJAMES WIMER, OF SAME PLACE.

BLACKSIVIITHS HEARTH.

SPECEFXCATION forming part of Letters Patent No 337,735, dated March 9,1886.

Application tiled October 12,1885.

To all whom it may concern:

Be it known that I, HENRY BRANCHLER, a citizen of the United States, anda resident of Greensburg, in the county of lVestmoreland and State ofPennsylvania, have invented certain new and useful Improvements inBlacksmiths Hearths; and I do hereby declare that the followingis afull, clear, and exact description of the invention, which will enableoth- Ic ers skilled in the art to which it appertains to make and usethe saine, reference being had to the accompanying drawings, which forma part of this specification, and in which- Figure l is a verticalsectional View of my improved blacksmiths hearth. Fig. 2 is a similarview of the same, taken at a right angle to Fig. l. Fig. 3 is a sideview of the tuyere, showing parts ofthe hearth broken away, and Fig. 4is a horizontal sectional view on line :r as,

Fig'. 3.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to blacksmiths7 hearths, and more especiallyto the tuyere part of such hearths, and it consists in the improvedconstruction and combination of parts of the same, as hereinaftermorefnlly described and claimed.

In the accompanying drawings,'thc letter A indicates the brick-supportfor the hearth, and B indicates the bowl, in which the fire is kept, andwhich has the aperture O in its middle. The bowl has a neck, D, formedaround the aperture, which neck lits into a vertical chamber, E,which isprovided at its lower end with a slide, F, and which has the blast-pipeG entering its side near its upper end. Two rockshafts, H H, arejournaled in the upper end of this chamber immediately below the neck 4oof the bowl, and have two wings, I I, projecting into t-he chamber andnearly closing its upper end when placed horizontal, the rockshaftsbearing against the walls of the chamber. rIhe roclcshafts are providedat one end with cogged segments J, meshing with each i other, and oneshaft is extended and provided with a suitable handle or lever, K, forrocking it.

It will now be seen that as the rock-shafts 5o are turned to bring thewings to point down- Sera. No. 179,593. (No model.)

ward the aperture between them will beincreased, allowing a greaterquantity of blast to pass up-th rough the tire, and when the wings havebeen turned sufficiently down, so as to occupy a vertical position, ornearly so, the cinders from the re may fall down into the chamber, andbe emptied out by drawing the slide out at the bottom of the chamber, sothat the fire may be renewed or the cinders emptied out withoutdisturbing the irons which rest 6o in the lire.

The slide in the bottom of the chamber will prevent the blast fromescaping through the aperture in the bottom of the chamber, andV thechamber will serve to equalize the blast as it enters the chamber andlls the saine before ascending through the aperture at the top of thechamber, so that if there is any inequality in the blast it will not befelt in the iire, the chamber serving as a store-room for the blast, 7ofrom which it may pass into the tire.

The blast may be regulated by opening or closing the wings or gates uponthe rock-shafts, while still keeping theirinner edges sufficiently closetogether to prevent the cinders from falling through the aperturebetween them, and when the tire gets dull from accumulation of cindersthey may be dumped down into the chamber by opening the gates under theaperture of the bowl, when the cinders, which will 8o be immediatelyabove and upon the aperture in the bowl, will drop through the aperture,while the live coal and the coal which has not yet been consumed willremain in the bowl,and may be raked toward the middle of the same. Inthis manner the tire may be kept up continually without any necessityfor raking the tire ot'f from the hearth for the purpose of cleaning theaperture in the bowl, and the iire may be relieved from cinders withouteven removing 9o the irons from the tire.

It follows that this hearth or tuyere may be used in a stationary hearthas is generally found in a blacksmiths shop, or it may be adapted to.iit into the several forms of portable hearths, my improvementsbeingindependent of the means for creating the blast, as well as of theshape of the bowl and its support, being adaptable to any constructionof bowl and support.

IOO

I am aware that it is not new to provide a blaeksmiths tnyere withpivoted gates' 'or doors by vmeans of which the draft can be regulated,and I do not claim such construction, broadly; but

I claim and desire to secure by Letters Patent of the United Statesl'.Inahlaeksmithstuyere,thecombination, with the bowl having t-he aperturein its iniddle, of two downwardly-opening gates having cogged segmentsupon their pivotal shafts meshing with each other, said gates being soarranged that their edges always approach each other directly underneaththe middle of the aperture in the bowl, as and for the purpose shown andset forth.

2. In a blaoksniiths tuyere, the combination of a bowl having anaperture at its iniddle surrounded upon its underside with a neck orange, a downwardly-extending chamber having vits upper end fitting' uponthe neck, and having the blast-pipe entering its side near the upperend, and having an aperture at its lower end, two rock-shafts journaledin the upper end ofthe chamber, bearing against the sides of thechamber, and having `vWings upon their inner portions for closing thechamber, and having eogged rsegments upon their shafts meshing with eachother, and means for rocking` them, and a slide covering the aperture inthe bottom of the chamber, as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto aixedmy signature in presence of two Witnesses.

HENRY BRANCHLER.
